Hormone testing?

Hi all! I did a search for the word hormones and saw there are lots of memebers who experience hormonal issues. I couldn't find anything similar to mine, so I wanted to reach out for some advice.

Background info: I'm 32, 2 young kids, have not been on any sort of birth control since 2007, have been told by sister that our mom has been diagnosed as depressed but she refused to take anything for it, and I have been counting calories and exercising (for real) since January of this year. I have a regular cycle, approx 23-25 days apart.

Prior to having kids, my husband and I had a pretty good relationship and active sex life. Normal relationship woes, but nothing major, ya know? This past year has been rough. Mentally I feel like there is something wrong me and my desire to have sex is like zilch. When we do attempt it, I feel like it something I have to cross off my "to do" list and can't wait until it is over. Sometimes it is even painful, but I honestly thought perhaps it was from in-activity? Besides the physical, I just go through these phases of feeling angry, anxious, depressed, stressed, and like completely indequate as a mom and wife. I say phases because I don't ALWAYS feel that way, but it seems to be happening more frequently. I do notice I get even more stressed and crazy-feeling the week before Aunt Flo comes to visit. But I hate using that as a crutch when it seems like it affecting me all 23 days inbetween. I know with school starting I have been stressed, but it seems like there is always something stressing me out.

edited to add: One of the reasons I started MFP is to feel better about myself, hoping my self-image and exercising would assist in how I felt and who have a positive impact on my marriage. I have lost about 10 pounds, have began dressing better, bought new clothes, wearing make-up. But still feel anxious, stressed, and have a low limbido.

My husband doesn't understand, he is really not feeling great about our marriage and keeps thinking it something he is doing. He has really stepped up his game trying to help out around the house and other stuff, but nothing is making me want to have sex with him. I have tried to tell him that I think it is me, but he seems to think it is all about him and that I don't love him anymore. After we had this convo recently, I called my OBGYN and made an appt to maybe have some bloodwork done. And I also WANT to take birth control or get an IUD. I don't want any more kids and when we DO have sex I hate having to stop everything to grab a condom- completely a mood killer. But on the other hand, all I have read about and even the hubby who says he has done "research" is that often BC can be one of the reasons women experience a lower limbido, which I obviously don't need assistance with!

My appt with my OBGYN is Monday - got any advice on what sort of test I should be asking for? What sort of information I should make sure she knows?

I also have been looking at counseling, but that is a hard step to take. I did call one lady's office that is near my work, but I had to leave a message and have not heard back yet. I know I would probably have to take time off work once a week to do that and not sure how much that would cost, and that is just another thing that stresses me out!

If you got this far, bless you! Thanks in advance!
